2000 C5 had starter go bad & I am replacing. I'm thinking of replacing Crank Sensor while down there. Is anything needed as far as a relearn for sensor replacement or is it just remove the wire, 1 bolt, pull out old , insert new & that's it? I was getting a intermittent code P 1637 both H & than H C when running. I found really loose connection at starter that crumbled in my hand when checking it. Plastic that held batt bolt cable to solenoid probably got heat destroyed from LT headers after 11 years.

I've replaced the crank sensor on my car with no relearn procedure. No problems at all.

Nice that's what I was hoping to hear. I wouldn't want to put it all back together & not be able to start. Than I would have to be towed into the shop.

The FSM calls out for 3 separate relearn activities. I imagine over some driving time you don't need them. If you want them I can provide them later.
